Although I design systems using 2kW – 9 kw inverters I often recommend to my clients to use several small inverters, each dedicated to one task. Inverters are most efficient when loaded to 80 – 90% of their rated capacity. Thus it makes no sense to run a 300 – 600 watt load with a ginormous 2kW or bigger inverter.
